USB: omninet: fix write_room
commit 694c6301e515bad574af74b6552134c4d9dcb334 upstream. Fix regression introduced by commit 507ca9bc047666 ([PATCH] USB: add ability for usb-serial drivers to determine if their write urb is currently being used.) which inverted the logic in write_room so that it returns zero when the write urb is actually free.
